VAPOR-GENERATOR.

To all whom it may concern Be it known that we, RiojnAnn A. I-lons'r and JULIUS C. Gonnnn, citizens of the United States, residing at St. Louis, State of Missouri, have invented certain new and useful Improvements in Vapor-Gwen ators, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

Our invention has relation to improvements in vapor-generators for generating vapor from hydrocarbons used in lighting and. heating or for other purposes; and it consists in the novel details of construction more fully set forth in the specification and pointed out in the claim.

In the drawings, Figure 1 is a front elevation of our invention, showing sections of the walls of a box (not otherwise shown) to which the same is secured, parts being broken; Fig. 2 is a vertical cross-section on the line 2-2 of Fig. 1 showing also feedvalve casing in section; Fig. 3 is a horizontal section on the line 3-3 of Fig. 1; Fig. 41 is a vertical section on the line 4-4: of Fig. 5; and Fig. 5 is a top plan of the vapor-generator burner and alcohol basin surrounding the same.

The object of our invention is to construct a vapor-generator which will supply the vapor at a substantially uniform pressure so that there shall be no fluctuation at the point of consumption, especially where such vapor is used for lighting purposes.

A further object is to provide a generator which can be readily manipulated, the parts thereof being all readily accessible; one which is simple, cheap to construct, strong, durable and reliable, and one possessing further and other advantages better apparent from a detailed description of the invention which is as follows Referring to the drawings, B, B, represent port-ions of two opposite walls of a box or cabinet in which the device is mounted. the air-intake pipe or elbow of the generator being alone allowed to project out of the box. The box itself is not shown as itforms no part of the invention. Between the box-walls aforesaid is secured a strap a which in the main serves as a support for the generator. To this strap is secured the vertical hollow feed-leg 1 of the generator,

said leg terminating at the bottom in a reduced extension 2 closed by a conical plug 3 the outer stem 4 of which passes through ,a securing nut 5 screwed over said extension, suitable washers w, 10. being interposed between the strap a and base of the leg 1, and a thin nut 6 being screwed over the extension against the strap a from below. The plug makes a tight joint against possible leakage of the gasolene (or equivalent hydrocarbon) and may be removed conveniently to allow for cleaning the passage of the leg 1. At the base of the leg 1 proper and above the extension 2 thereof, are formed screw nipples 7, 8, respectively, extending in opposite directions, the former serving as a means of connection with the hydrocarbon supply pipe 9, and the latter for the reception of the screw-feed valve 10, a suitable packing nut 11 being screwed over the end of the nipple as shown (Fig. 2), the outer end of the stem of the valve being provided with a disk or hand-wheel 12 by which the valve may be manipulated. This valve controls a port 0 in the base of the nipple 7, said port establishing communication between the passage of the leg 1 and the source of supply. the rate of supply being regulated by said valve 10.

Cast with the upper portion of the vertical leg 1 is a horizontal tubular leg 1 preferably reinforced by ribs 9', 1", the passage in said. leg 1 communicating with that of the leg 1, the upper end of the passage of the leg 1 being closed (above the point of intersection of the respective passages, of course) by a screw-plug 13. The free end of the leg 1 terminates in a T 14 to the depending leg of which is screwed the casing 15 of a needle valve 16, the stem of which passes through the strap a and terminates in a handle 17, and is otherwise of a construction well understood in the art. The upper leg of the T 14 discharges its vapors through a tip 18 which discharge is directly controlled by the needle-valve 16. The vapors from the tip 18 discharge across a mixing chamber 19 into which the necessary complement of air is drafted through the elbow or air pipe 20 (allowed to project out from the wall of the box B), the mixture thence flowing to the general service pipe P through the union or pipe connection 21 screwed into the wall of the mixing chamber, and itself being screwed into the base of the pipe P, the special and preferred form of connection being as shown (Fig. 1). Opposite the point of discharge from the pipe 21, the service pipe P is tapped by the upper end of a shunt 22, the lower end of which carries an elbow 23 to the discharge leg of which is screwed a generator burner 24 (terminating in a series of burner-openings b, Fig. 5), the walls of the burner having cast therewith an annular trough 25 serving as a preheating basin, the burner and its basin being directly under the leg 1 and its heatabsorbing and stiifening ribs 7", r. The shunt 22 by reason of its proximity to the formations or ribs 9" becomes more or less heated by the heat radiated from the ribs, thus raising the temperature of the gas which supplies the burner 24:.

The operation of the generator is substantially as follows :The port 0 is first closed by the feed-valve 10, and some alcohol or other hydrocarbon is poured into the basin 25 around the burner 2 and ignited. This serves not only to preheat the walls of the generator-burner 24, but the walls of the leg 1 (and its ribs 0, 7'), said leg serving as the generator-member proper since it is in this leg that the inflowing gasolene is converted into vapor. The walls of the leg 1 being sufficiently heated, the valve 10 is now manipulated to open the port 0 and admit the gaso-lene from the pipe 9, the gasolene finding its way through the leg 1 to the leg 1 where it is vaporized by the heated walls of the latter leg, the vapors passing on through the T 14: and tip 18 into the mixing chamber 19 when the proper complement of air mixes with the vapors, the mixture passing up into the service pipe P. A part of this mixture is obviously shunted through the pipe 22 to the burner 24 where it escapes through the perforations b, and where it ignites either from the flame of the still burning alcohol in the basin 25 surrounding the burner, or by means of a match if the alcohol has burned out. The burner flame now permanently impinges against the walls of the generator leg or member 1 and vaporizes the gasolene as fast as it flows through said leg. The hot vapor thus mixing with the air supplies the riser P and may be used for heating or lighting, a certain amount being of course continuously shunted through the pipe 22 to supply the generator-burner 2 1. The regulating valve 16 need not be closed at any time, but may be set to any desired position to regulate the stream of vapor through the tip 18.

Having described our invention, what we claim is In combination with a vertically disposed hydrocarbon supply pipe, a vapor generator leading from one end thereof at substantially right angles thereto, a mixing chamber into which the generator discharges,the latter being provided with outer heat-absorbing and heat-radiating formations, an air intake for the mixing chamber, a service pipe leading from the mixing chamber, a burner positioned centrally beneath the generator, a shunt leading from the service pipe to the burner and disposed in proximity to the heat-absorbing formations of the generator so as to receive the heat radiated therefrom, a starting basin surrounding the burner to preheat the walls of the burner and generator, and a valve controlling the discharge from the generator into the mixing chamber.

In testimony whereof we aflix our signatures, in presence of two witnesses.
